Abstract In the light of the recent report by the ALEPH Collaboration [D. Buskulic et al., Phys. Lett. B 365, 437 (1996)] where Lambda /sub b/ polarization was measured, which involves polarization transfer from the b quark to Lambda /sub b/, we discuss the gluon circular polarization created in high energy e/sup +/e/sup -/ annihilation, previously calculated, and give a calculation of gluon circular polarization creation in high energy electron-proton collisions. For high energies the gluon circular polarization is sizable and the polarization is directly transferred to qq-vector mesons. We give energy spectra and angular distribution of the gluon circular polarization for various initial energies. Gluon elliptic polarization, inferred from linear and circular polarization, is displayed for two initial energies. (11 refs).
